Legally obliged to jump across (5,4)
I believe the answer is:
bound over
'legally obliged' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'jump across' is the wordplay.
'jump' becomes 'bound' (synonyms).
'across' becomes 'over' (synonyms).
'bound'+'over'='BOUND OVER'
'to' is the link.
Can you help me to learn more?
(Other definitions for bound over that I've seen before include "subject to legal constraint" , "Put under a legal obligation" , "Placed under a (specified) legal obligation" , "Legally under restraint - jump across" , "Clear" .)
